C3021N Metal Handle 20mm Travel 8.1 Mm Wide Used For Sound Console Earphone And Microphone
Working principle of potentiometer: composed of resistance body and rotation or sliding system, namely by a moving contact moving on resistance body, obtain partial voltage output
1, used as a voltage divider
A potentiometer is a continuously adjustable resistor in which moving contacts slide on the resistor body when adjusting the potentiometer's turn or slide handle. At this time, the potentiometer output terminal can be obtained and potentiometer applied voltage and movable arm Angle or stroke into a certain relationship of the output voltage
2. Used as rheostat
When potentiometer is used as rheostat, should connect it into two ends device, inside the range of travel of such flower potentiometer, can obtain the resistance value of a smooth and continuous change
3, used as current controller
When the potentiometer is used as a current controller, one of the selected current outputs must be the sliding contact leads
